外弹道课程设计，建立六自由度仿真模型，在无控的状态下，利用matlab编程仿真计算航空炸弹的投放域。得到导弹的速度时间关系图像，攻角与时间关系图像。(In the course design of external ballistics, a six-degree-of-freedom simulation model is established. In the uncontrolled state, the airborne bomb dropping area is simulated by MATLAB programming. The velocity-time relationship image and the angle of attack-time relationship image of the missile are obtained.)

说明：  SRIO编程参考说明，工具书,非常适合初学者。建议入门前先了解。(SRIO programmer designed manual)

求解随机微分方程dx=sinxdt+xdw的数值解(NUMERICAL SOLUTIONS FOR SOLVING STOCHASTIC DIFFERENTIAL EQUATIONS dx=sinxdt+xdw)

说明：  产生复高斯的白噪声,这和matlab 自带的不一样，容易理解，但是经对比还是和自带的有区别的(AWGN noice we are very nice. please try to run it snd you will find you are good too.)
